NEEDLE THREADEB.

Application filed April 9, 1921.

To all whom it may concern:

Be it known that I, ALBERT C. VANEPKA,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois. have invented a new and useful Improvement in Needle Threaders, of which the following is a specification.

An object of this invention resides in the production of a needle threader having a novel sliding threading member cooperating with an improved needle and thread retaining means. 7

It is also an object to provide a device of this character which shall be simple and iu expensive to manufacture.

lVith these and other objects in view my invention consists in the novel construction, combination and relative position of the parts and members hereinafter described and shown in the accompanying drawings, and particularly pointed out in the appended claims.

' Referring to the drawings in which like reference characters indicate like or corree5 spending parts:

Figure 1 is a plan View of a needle threader embodying my invention. Figure 2 is an end elevation thereof. Figure 3 is a longitudinal section taken on line 33 of Figure 1, and Figure 4: is a sectional plan taken on line e 1 of Figure 2 showing the threading member in operative position.

Figure 5 is an enlarged cross section taken on line 55 of Figure 1, and Figure 6 is an end View of the needle-supporting arm.

Figures 7 and 8 are respectively enlarged side and end elevations of the end of the movable threading member.

Figure 9 is an enlarged detail of my improved threader showing the operative position of the threading bar in dotted lines. i igure 10 is an enlarged sectional view taken on line 1010 of Figure 9. Figure 11 is an enlarged cross section taken on line l1-11 of Figure 9, and Figure 12 is a view in perspective of the bracket 21.

Referring to the illustrations, 10 indicates a longitudinally slidable threading plate provided with an extending integral operat ing bar 10 and having a long integral threading member 10 of comparatively narrow width to permit its passage through the eye of a needle 11. The threading plate 10 is slidable between the supporting body 12 and the cover plate 13 which is formed with is bent at an angle to provide an angular Serial No. 4.593%.

longitudinal bent edges 13 adapted to embrace the supporting body 12 and thus confine the threading plate therebetween. Normally the cover plate 13 rests with the end integral flange stop 14 against the end of the supporting body 12.

The needle 11 is shown resting against the narrow side retaining bar 12 which is formed oi? a narrow integral right angularly disposed extension of the body 12. G5

.The eye end of the needle rests against the abutment bar 12 which is also formed of an upwardly bent narrow strip integral with the body 12. The other end of the needle is supported on the Lshaped end 15 of the supporting arm 15 which is curved as at 15 to attord thumb clearance for the insertion and removal of the needle. One end of the bar 15 is rigidly secured to the plate body 12 by rivet 16.

Additional needle retaining means are provided in a wire spring 17 which is firmly attached at one end to the screw 18 mounted in the ear 15 which car is formed integral with the arm 15. The upper end of the Wire spring 17 projects through an opening extending through the plate 12 and arm 15. It is thus evident that the needle isnormalty confined between the upper free end of the spring 17 and side bar 12.

The cover plate 13 and the body 12 are respectively recessed at 13 and 12 and it will be observed that both recesses are in alignment or register and have the left hand side located slightly to the right of the end of the. threading member 10 when such member 10 is in its normal back position (see Fig. 1) ready for the forward threading movement. It will also be observed that the recesses 13 and 12 are cut inwardly to a distance slightly beyond the center line of the threading member 10 so that when the thread is passed into the recesses the thread will be in alignment with the center line of the threading member 10.

In order to guide and facilitate the passing of the thread into the recesses 13 and 12 and also to retain it, I have provided a wire spring guide 20 one end of which is secured by the rivet 19 to the bottom of the body 12 and the free end 2O being movable under the integral extension 21 of the supporting bracket 21 which is also riveted to the body 12. The intermediate portion 20 guide for the thread to the recesses mentioned. The upper .portion of theebracket is formed with anaintegral ear;21 which supports the over-hung portion of the. spring guide 20.

Additional thread retaining means are provided in spring pressed button retainer 22 which comprises a stationary disk member 22 having riveted connection 22 with the cover plate 13 and a stub extension 22 on which lie loosely- :monntedi the retaining disk 622 l.lie.disk:122 is dished, 1 as" shown in Figure 5,..to aecommodate the leaf spring v22 which .is held? to the stnbQQQ by. the; tap screwzQS. It .iszobvious that the springQQ will retain the twolfdisks HIId'JQQ tO- gethcr andithat the thread can be readily passed over their beveled edges between them for retainment.

Re terring particularly: to Figures 7 r and '8 which showrairenlarged detail of theend ot' the threadingmember .10, it will be noted that flat bar l0 .;:is small enough to pass through 1 the needles eye; that it is recessed at the end: asaat: Qtto' provide a socket for the thread, and. that longitudinal-slots 25 arecut back in the sides oi the bar: 10? from the recess 2. L The slots :25-zarefip-referably formed of a converging section both in width and length. The. provision otthese slots 25 permits the passage ottheuthread .atnd eo-opemtingv with said arm support and said needle retaining means on said body "for releasably retaininga needle, a-coinparatively long and-narrow threadingbar slid- .ablyimounted-between said body and-said cover plate, a re tess-in-said body, a recess liH'Sait-l cover plate, said'recesses being in registerand adapted to engage the thread in the direct pathof the threading bar: -forcn- ,gageinent thereby, means for drawing said threadingbar and thread throughthe eye of the needle,spring-means forreleasably holding the thread between said recesses, and said needle retaining means-on said 'bodycomprising' an integral side bar-and an integral abutment bar.

2. The needle threadeimas specified in claim 1, in combination with spring means iior -releasably holding the thread between said recesses.

In witness whereof, Lhave hereuntosubscribed my name.
